Background

Status: Approved

Sponsor: Jackie Ashbaugh on behalf of the MIS Users Group
Urgent: Yes

Description: This SCR proposes the development of a new wind aggregated dashboard available to the public that displays the following on both the system-wide and regional level in graphical form: Aggregate Wind-powered Generation Resource (WGR) Power Output Aggregate Short-term Wind Power Forecast (STWPF), from both the current and Day-Ahead Aggregate Wind-powered Generation Resource Production Potential (WGRPP), from both the current and Day-Ahead Aggregate Current Operating Plan (COP) High Sustained Limits (HSLs) for On-line WGRs, from both the current and Day-Ahead System-wide and regional WGR output data would also be displayed on the dashboard. These values will update with each Security-Constrained Economic Dispatch (SCED) run and represent a current snapshot of the aggregate WGR output.
Reason: This SCR will provide a public graphical representation of the amount of wind generation forecasted and produced in the ERCOT Transmission Grid for all markets. With substantial amounts of wind capacity located in ERCOT, the ability to view wind generation in near Real-Time will allow Market Participants and consumers to anticipate the impact of variations in wind production on market prices. Timely information about how actual wind production compares to forecasts will help Market Participants manage the resulting market fluctuations. Wind power brings unique challenges to the electrical market. A public dashboard would help the market adapt to deal with these challenges.
